And the tunneling effect of wave packet is analyzed concretely.

并具体分析了波包的隧道效应.

By analyzing intuitional images presented in this work, the dynamical process of wave packet is investigated.

通过分析文中的直观图像，研究了波包的动力学过程。

And try to establish a model of standard deviation of wave packet by using statistical methods.

接著利用统计的方法，建立出波包标准差以及各外加条件的模型。

If we keep adding waves, we can make a wave packet with a clear wavelength in one small region.

如果我们持续添加更多的波，我们能得到一个波包：在一个很小的区域里有一个确定的波长。

If you want to know the momentum better, you need a bigger wave packet, which means a bigger position uncertainty.

如果你想更明确的得到动量值，就需要一个更大的波包，这样就导致了更大的位置的不确定性。

As the optical precursor and main wave packet traveled through a second group of rubidium atoms, the scientists took measurements on the speed of the two photon components.

随着光前驱和主波包通过第二组铷原子，科学家就可以对这两个光子成分的速度进行测量。

The detection of a highly vibrationally pump-dumped iodine wave packet dynamics in the ground X state is numerically demonstrated by using a model I2 molecule with two Morse potential surfaces.

在数值计算中，采用I2的一个二势能面系统，得到了监测基电子态高振动激发波包的吸收光谱。

The atoms had an effect called electromagnetically induced transparency (EIT), which enabled the scientists to separate the single-photon precursors from the main wave packet.

这些铷原子可以产生一种称为“电磁感应光透明”（EIT）的效应，可以帮助科学家从主波包中分离出单个光子前驱。

But this study is the first to experimentally show that optical precursors exist at the single-photon level, and that they are the fastest part of the single-photon wave packet.

而这次的研究则是第一次用实验证明，在单个光子层次上也存在着光前驱，而且它们也是单个光子的波包中最快的部分。
